Matlab数字图像处理,GUI界面,可以运行,载入图象后进行变换(Image traslation based on Matlab)

压缩感知基追踪算法，实现二维图像的小波变换以及图像重构(Compressed sensing based tracking algorithm, wavelet transform two-dimensional image, and image reconstruction)

图像经过Contourlet变换后，加水印(After Contourlet transform images, add watermark)

说明：  根据文献Verification of color vegetation indices for automated crop imaging applications所述方法实现的可见光（RGB）的植被提取，效果非常好，压缩文件内附有该文献英文原文，以及部分供测试图片。(According to the method described in the document verification of color vegetation indexes for automated cross imaging applications, the effect of vegetation extraction of visible light (RGB) is very good. The original English version of the document and some test pictures are attached to the compressed file.)

用斯托克斯矢量法，计算偏振度图像和偏振角图像，方便进一步处理。(Degree of polarization and angle of polarization calculating)

说明：  matlab code for optimization

这是一个专门为菲涅尔衍射设计的一个仿真程序！参考光为平面波！本人测试过，没有问题存在！(This is a design specifically for the Fresnel diffraction of a simulation program! A plane wave reference beam! I tested, no problem!)

基于半色调图像的数据隐藏即加数字水印，针对半色调图像，所以使用的是DHSPT算法，算法较容易理解，简单，嵌入效果相对较好(Hidden based on the halftone image data plus digital watermark for halftone images, use DHSPT algorithm, the algorithm is easy to understand, simple, embedded effect is relatively good)

SIFT特征提取演算法(包含匹配以及除错机制RANSAC)-可用于两张影像之特征点匹配 (SIFT feature extraction algorithm (including the match, as well as debug mechanisms RANSAC)- can be used for two images of the feature points matching)

二维的OMP算法，封装完成的函数，可独立调用(Two dimensional OMP algorithm, wrapped function can be called independently.)
